Parts Help

I have a set of Pro Torker 12400 and they have slotted pushrod holes .The sheet in the box says not to use guideplates and to use the stamped steel rockers.

My questions are:

What studs should I buy so I can use the oem nuts balls and rockers?

Do I need hardened pushrods?

Should the rockers be the non self aligning type??

Thanks

Wow, Sure is lonely in here.
